Jennifer Matthews: This is Ricky Leon. His face marked by a congenital nevus, an abnormality that affects nearly three million Americans in the US. Dr. Kian Samimi: It looks like either a brown spot or a black spot and they do grow at the same rate that the child grows. Juan Leon: When he started going to the school, the other boys was telling him, your nose is dirty. Jennifer Matthews: His parents couldn't help him, but Dr. Kian Samimi could. He used a technique called tissue expansion. Today, Ricky bears only the scar of the procedure. Dr. Kian Samimi: Tissue expansion is the next best thing that we have to growing new tissues. Jennifer Matthews: Standard treatment takes a skin graft from another area of the body, but different parts of the body have different colors and textures. Now patients have another option. Dr. Kian Samimi: We place the tissue expanders underneath the skin that is not involved with the nevus. Jennifer Matthews: Over time, the expander is filled with saline. When there is enough excess skin, the expander and the discolored skin are removed and the new skin is pulled over the defect. It worked for Ricky and his dad couldn't be happier. Juan Leon: He's a very good student and he's a very good son and we love him. Jennifer Matthews: With his head held high, Ricky is now ready to tackle life, face first. This is Jennifer Matthews reporting.
